Because of the wide variety of machining applications, there is a need for diverse cutting tool materials. Part of the Fundamental Manufacturing Processes Video Series, this program provides a broad understanding of the development of these tool materials, focusing on high speed steel tools, carbide (including its property variables, types, grades and coatings) ceramic, cermet, and superhard materials like cubic boron nitride, or CBN, and polycrystalline diamond (PCD).
